Section : Actions that Void the Fast.The actions that void the fast may be divided into two types: 1. those which void the fast and require that the day be made up later, and 2. those which void the fast and, in addition to being made up, also require an act of expiation.
Section : Intentional eating or drinking.If one eats due to forgetfulness, a mistake, or coercion, then he does not have to make up the day later or perform any expiation. Abu Hurairah reported that the Prophet said: "Whoever forgets he is fasting, and eats or drinks is to complete his fast, as it was Allah … Continue reading Fiqh-us-Sunnah Volume 3, Zakaat and Fasting, Fiqh 3.138A.
Section : Fasting, intentional vomiting.If one is overcome and vomits unintentionally, he does not have to make up the day later on or perform the acts of expiation.

Section : Fasting, the menses and post-childbirth bleeding.Even if such bleeding begins just before the sunset, the fast of that day is rendered void and the day must be made up. There is a consensus of scholars on this point.

Section : Eating something that is not nourishing, such as salt.Someone who uses a lot of salt for a reason other than eating, in which it goes down to the stomach, breaks the fast according to most scholars.
Section : If one has the intention, while he is fasting, to break the fast, he in effect voids the fast even if he does not actually eat anything.This is because the intention is one of the pillars of the fast and, if one changes his intention, he has nullified his fast.
Section : If one eats, drinks, or has intercourse, thinking that the sun has set or that fajr has not occurred.In such cases, according to most scholars and the four imams, that person is to make up that day. However, there is a difference of opinion on this point. Ishaq, Dawud, Ibn Hazm, 'Ata, 'Urwah, … Continue reading Fiqh-us-Sunnah Volume 3, Zakaat and Fasting, Fiqh 3.139D.
Section : Unintentional mistakes.The Messenger of Allah, upon whom be peace, said: "Allah will not hold anyone of this nation responsible for what is done by mistake..."'Abdurrazaq related that Mamar reported from al-Amash that Zaid ibn Wahb said: "The people broke their fast during the time of 'Umar ibn al-Khattab.
